Vercel deployments broken with pnpm

[sammccord]

What version of astro are you using?

1.4.6

Are you using an SSR adapter? If so, which one?

Vercel

What package manager are you using?

pnpm

What operating system are you using?

Linux

Describe the Bug

When deploying an Astro site inside a pnpm monorepo to Vercel with the @astrojs/vercel/serverless adapter, the deployment succeeds, but all requests fail with 500 errors. See this deployed example - https://pnpm-astro.vercel.app/

The only error being thrown in the logs is:

ERROR	Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@astrojs/vercel' imported from /var/task/entry.js    at new NodeError (node:internal/errors:372:5)

This is essentially a duplicate of #4567, but I'm re-opening this specifically for pnpm / Vercel functionality.

I'll also note that shamefully-hoist=true in the root .npmrc doesn't seem to have any effect, even though it was fixed in >1.4.0

Do you need to move that package into a regular (non dev) dependencies?

Both astro and @astrojs/vercel are listed in the package's production dependencies in the attached reproduction - https://github.com/sammccord/pnpm-astro/blob/main/packages/astro/package.json

@sammccord I've made a fix. Could you try it and tell me if it works?

$ pnpm add @astrojs/vercel@next--monorepos
